CARPENTER'S WORKHOLDER.

' Application med october 31, 1923. serial No. 671,967.

To all whom it may con-cern: Y

Be it known that I, OoTAvE BUREAU, a citizen of the United States, residing vat Waterville,in the county. of Kennebec and State of Maine, have invented certain new and useful Improvements in a Carpenters IVorkholder, of which the following is a jed for use by carpenters which embodies a cooperative arrangement of vise and adjustf able clamps and stops.

A further object of this invention is the provision of a carpenters work holder which embodies a compact arrangement vof work handling devices conveniently assembled in a cooperative relation, and in this respect differing from the present work handling devices ofcarpenters which are yscattered about the oarpenterls bench, taking up much roomr and rendering it difficult to lperform some operations in a facile and expeditious manner. j f

, Afurther object of this invention'is the provision of a novel type of adjustable bench stop.

Other objeotsand advantages of this invention will be apparentduring thecourse of the following detailed description.

In the accompanying drawings, forming a part of this specification, and `wherein similar referencecharacters designate corresponding parts throughout the several VIEWS.

Carpenters bench, and'which may includer a -vise construction C, and novel adjustable bench stop or abutment construction D..

The vise structure C isof novel construction, embodyingI a'supportingbox or casing of elongatedformation, which provides a compartment 11 therein." It includes the side walls'12 and 13;` a top wall 14; and one yendvwall 16 preferably having anopening 17 therethrough. The front of the hous-k ing 10 is preferably provided with astationary jaw 2O flanged thereon vat right angles tothe run of the b0X10; the compartmentll preferably being entirelyopen at. the front of the box 10 adjacent the stationary jaw 20.

A slidable jaw structure 21 is provided for Cooperation with the `above described structure of the vise C, which yincludes a substantially U-shaped elongated casing 23 adapted for sliding'engagement in the compartment 11 of the vise casing or box 10; and the jaw 25A which may be appropriately termed the sliding jaw of the vise C. rlhe U-shaped sliding portion 23 of thefsliding jaw structure 21`preferably is polygonal in its U-shaped cross section, providing the side walls `27 a top wall 28; and av reary wall 29 having an opening 30 therein rin aligning relation with the opening 17 above mentioned. Thesupporting casing 10 of kthe vise is preferably provided kwith a transverse supporting bar 33 integral therewith intermediate its ends, and at the bottom thereof, upon which thek sliding portion 23 of the jaw structure 21y rests'. `Also, raV transverse bottom bar 35 is provided integral with the casing structure 10, adjacent ther stationary jaw 20, upon which the lower edges of the sidewalls 27 slide to also support the sliding jaw in a determined'relation ywith respect to the stationary jaw structure of the vise C. y A f y A screw 40 is rotatably supported bythe sliding jawk structure 21, having'k a bearing in ing jaw 25; outwardlyof the ysliding jaw 25 having a suitable handle 42thereinof the well knowntype. The screwthreaded Lportion of the screw member 4()k extends lon- In connection with the attachment Vof the j vise structure C to the work bench B, a. supporting arm 50 is preferablyv provided a jacent the rigid jaw and integral therewith, ofset as by aiiange 51 from the plane of the stationary jaw 20, so that the supporting arm 5() may overlie the rear of 'a side wall 52 of the bench B, and be bolted thereto as by bolts 58, or the like. Itis to be noted that the marginal edge of the bench wall 52 then restsagainst theoset flange 51, so that the work engaging surface ofthe stationary jaw 2O lies flush withv the outside surface of the bench wall 52, substantially as is illustrated in Figures 1 and 8 of the drawings.

. A second supporting arm 54 is vpreferably provided in connection ywith the vise B, which provides a socket 55 at its outer end adapted to receive the rear portion of the vise box or casing 10 therein. AtV its other end the supporting arm 54 may be bolted,

as at 56, beneath the tableY or top 57 of the' bench B. A suitable opening 59 may be provided in the socket portionjof the supporting arm 54, adapted to align with the opening 17 of the vise casing 10, and thru which the adjustment Iscrew 40 may pass during adjustment kof the jaws of the vise into a certain relation. Y

The sliding jaw is of somewhat novel formation, providing a portion 25Z1 with a working surface which is disposed in a parallel plane at all times with respect to the plane of the stationary jaw 20. However, at the lateral portion of theslide jaw 25, a portion 25b thereof is outturned at an obtuse angle with respect to the portion 25, so that the plane defined by the portion 25lJ is inv acute angularrelation with respectto the plane of the stationary aw 20, and prov` vides a wedge crevis 4with respect to the stationary jaw 20, 'adapted to receive pieces of work in working relation therein, similar to the bench stops now used by carpenters Referring to the adjustablebench stop or abutment device the same preferably includes a frame 60, whichy consists orf Vupper and lower horizontal bars 61 and 62 respectively, connected at their ends by means of vertical'cylindrical shaped posts 64 and 65. 'l'he posts 64 and 65 are each slidably dis posed through laterally extending guide lugs 66 which are integrally carried asa part of the vise housing 10, extending laterally of the side wall 13 thereof. The frame 60. is vertically adjustable, and to this" end rotata-v bly` carries an adjusting screw 7 0,'which is rotatably supported in a suitablel bearing ybetween the ends of the lower bar 62. Below the bar 62the screw70provides a crank 71. The threaded portion of the'sc'rewv70 threadably engages'through 'a laterally ex tending lug 73 [which maybe integrally Casing 10,

formed withrespect to the'vise housing or4 ythe vise C is preferably provided with a fixed jaw 75 disposed in a vertical plane; said jaw r 7 5 being in such a rela-tion to the work bench B, that the same does not interfere with the table portion 57 thereof, and is disposed rearwardly of the attaching ends ofthe supporting arms of the tool A, and in the space'between said supporting arms. An adjustable jaw 76 is slidably carried by the upper horizontal bar 61, providing a face portion 77 which is disposed in a plane at an acute angle with respect to the work engaging face of the fixed jaw 75. The jaw structure 76 provides a socket portion 78 which has an opening 78a therein which slidably receives the bar 61, and this socket portion 78 preferably has an opening (not shown) therein which may align with any of a series of openings 79 disposed longitudinally in the bar 6l, so that a cotter pin 8O may be inserted therethrough to lock the jaw structure 76 in a fixed relation to the bar 61 and to the j aw 75. *Y

The fixed jaw structure 75 preferably provides a fixed shelf 82 thereon, adjacent the marginal edge of the table 57 ofthe work bench B, to which may be suitably clamped, a notched plate or toothed bench hook or stop 85, as by screws 86.

Referring to the operation of the iinproved work holding device A, the jaws 2() and 25 thereof may of course be used'in much the saine manner as the ordinary vise, although the jaw 25 presents a. novel 'feature in the provision of the angled portion 25", which can cooperate at anV 'acuteangle with respect to the fixed jaw 20 in providing an adjustable stop for work engaging purposes. By means of vertical adjustment of the frame 60 it can readily be understood that the jaws 75 and 77 may be elevated to the desired degree7 and the jaw 77 slid along the bar61 with respect to the jaw 75 to the proper degree to receive a piece of work of a predetermined size 'for planing or the like thereof. The provision of the notched plate 85 Vis a novel feature of this invention, a-s it is not located in the top of the work bench B, but is adjustable with respect to the plane of the table 57 thereof for work engaging purposes, as will be readily vunderstood by those lskilled in the vart to which this invention relates.

From the foregoing description of this invention itwill be'apparent tliatthe improved device A4 provides acompact and simple arrangement of details which willpermit 'of the provision ofk a combined vise and adjust` ableV stop structure ofy a universal character, which may be attached to a carpenters bench o-r the like in an out of the way position.
